gastroduodenostomy
Pronunciation: gas-tro-du-oh-den-OS-toh-mee
Surgical creation of a connection between the stomach and duodenum to bypass obstruction or restore continuity.
Full Definition
A gastroduodenostomy is a surgical procedure that creates an anastomosis between the stomach and the first part of the small intestine (duodenum). This bypass procedure is commonly performed when the normal gastric outlet is obstructed due to peptic ulcer disease, malignancy, or congenital abnormalities. The procedure can be performed using various techniques including Billroth I reconstruction after distal gastrectomy. Proper terminology distinguishes this from other gastric bypass procedures.
Usage
Usage note: Distinguish from gastrojejunostomy, which connects stomach to jejunum.
